Description
Technical field
Preparation field more particularly to a kind of preparation process of martensitic seamless steel pipe the present invention relates to steel pipe.
Background technology
Martensitic stain less steel has good mechanical property and high-temperature oxidation resistance and corrosion resistance, so application range
It is very wide, but the preparation difficulty of martensite steel pipe is big, obtained martensite steel pipe is of poor quality, is not durable, Patent No.
The Chinese patent of CN102699103 discloses a kind of preparation method of 20CrMo steel pipes, processing step letter on October 3rd, 2012
It is short, it is beneficial to energy saving consumption, but in production process, often it is present with steel pipe internal-surface or outer surface longitudinal cracking, once
Cracking just can not carry out subsequent processing, cause the waste of steel, and martensite steel pipe obtained, hardness is very big, toughness
It is small, it is difficult to process again.For this purpose, applicant applied for a kind of horse of Application No. 2013105081890 on January 25th, 2013
The preparation method of family name's body steel pipe by the improvement to technique, solves the problems, such as the production of martensite steel pipe's production, and production cost is low,
Obtained martensite tube quality is good, and hardness is low, and toughness is high, is suitble to it is further processed.But the matter of Malpighian tube
Amount is still undesirable, and surface point is on the high side, and product fraction defective is higher.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of preparation process of martensitic seamless steel pipe, prepares
The bright and clean no pit point of martensite steel pipe surface that technique obtains, quality is good, promotes product lumber recovery, reduces production cost.
In order to reach the goal of the invention, the present invention adopts the following technical scheme that：A kind of martensitic seamless steel pipe
Preparation process comprises the following steps：1）Martensite steel pipe pipe centering, then into eleven punch 11；2）To the pipe after perforation
It is made annealing treatment；3）Pickling is carried out with pickle to the pipe after annealing, is then carried out successively at phosphatization, saponification and lubrication
Reason；Saponification liquor used in the saponification process includes petroleum sodium sulfonate, triethanolamine, oleic acid, dodecenylsuccinic acid, benzene a pair of horses going side by side three
Nitrogen azoles, machinery oil；4）By after lubricated pipe carry out hot rolling, carry out ageing treatment after cooling, obtain martensite steel pipe into
Product, the processing step of the ageing treatment are put into for a. steel pipe pipes in stove, and temperature rises to 45-60 DEG C, keeps the temperature 0.2-0.5h；b.
In-furnace temperature is risen to 150-180 DEG C, handles 0.5-1h；C. in-furnace temperature is down to 110-120 DEG C, keeps the temperature 1-1.5h.
Applicant has found that the outer surface pit point of steel pipe is on the high side, and such case occurs mostly in actual production
In step 3）Afterwards, in process below, these pit points can not also eliminate, in said program, by saponification
Liquid is improved, and can be effectively improved point situation, and combines the ageing treatment of segmented, and tube quality is stablized.
Preferably, the saponification liquor is by mass percentage, including petroleum sodium sulfonate 42-55%, triethanolamine 3-9%,
Oleic acid 15-20%, dodecenylsuccinic acid 1-8%, benzotriazole 15-20%, surplus are machinery oil.
Preferably, the pickle of the pickling is the mixed liquor of phosphoric acid, citric acid solution, Klorvess Liquid, it is described
The concentration of phosphoric acid is 10-15%, and the concentration of citric acid solution is 30-42%.
The pickle of said program can improve pickling effect, can the rust on fully erased pipe surface, oxide skin, and will not
Corrosive is generated, ensures the concentration of the quality, especially phosphoric acid and citric acid of steel pipe, pickling effect is influenced very big.
Preferably, phosphoric acid, citric acid, the volumetric mixture ratio of Klorvess Liquid are 3-5 in the pickle:2:1.
Preferably, the step 3）In pickling temperature for 38-45 DEG C, pickling time 20-25min.
With reference to the pickle of this programme, suitable pickling temperature can improve pickling effect, and pickling time is long to be caused
Steel pipe overpickling, the pipe surface of overpickling it is thick it is hot-tempered, color is dark, have circular pin hole when serious, easy roll banding or broken during cold rolling；Acid
Wash it is insufficient if cannot the rust on fully erased pipe surface, oxide skin, obtained steel pipe finished product resistance to corrosion is poor.
Preferably, the pipe after the hot rolling is carried out at timeliness again after thermal conduction plate and hot roll after natural cooling
Reason.
Preferably, before the phosphorating treatment, pipe is surface-treated using surface treatment liquid, the surface treatment
Liquid includes oxalic acid, glacial acetic acid.
The defects of corrosion caused by pipe pickling is uneven can be eliminated by carrying out surface treatment, be improved at phosphatization speed shortening
The time is managed, pipe is made to generate the uniform phosphate coating of compact crystallization in parkerizing process, while enhances corrosion resisting property and improves painting
Film adhesive force reduces phosphating dregs.
Preferably, the annealing carries out under vacuum, the pit of steel tube surface can be improved to a certain extent
Point defect.
Preferably, the vacuum degree of the annealing vacuum condition is at least 2 × 10-2Pa。
Preferably, the material nickel content that the thermal conduction plate uses is 5%-12%, hot roll material uses 2Cr13NiMo.
It has been found that the generation of pit point, except technologic influence, in Steel Tube Rolling, the thermal conduction plate of process
Influence is will also result in hot roll, the thermal conduction plate and hot roll used at present can cause steel bonding, and pit, shadow are generated in steel tube surface
Tube quality is rung, according to this programme, by the material of thermal conduction plate, hot roll, can solve the problems, such as this.
By implementing above-mentioned technical proposal, the present invention has following advantageous effect：The present invention is by rationally setting technique
Step controls the parameter in each step, and the bright and clean no pit point of martensite steel pipe surface, quality is good, promotes product lumber recovery, drop
Low production cost.
